To all whom it ma concern:

Be it known that we, Gnoncn B. BRAD- SHAW and WILLIAM H. BRADSHAW, citizens of the United States of America, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Chicle Substitute and Processes of Making Same, of which thefollowing is aspecification.

This invention relates to a composition of matter and the process for making the same, and with regard to its more specific features a substance having the desirable properties and features similar to chicle. 'Chicle, asis well known, is a plastic rubbery substance used for a number of purposes in various arts, but is perhaps most commonly employed as a base in the manufacture of chewing gum. This substance comes from Central ,American countries and is generally produced by coagulating the latex of the Sapota tree and is more or less expensive,

due to the difliculty in obtaining the same and the somewhat limited supply. It is also quite impure and dirty in its raw state, and

the necessary cleaning processes through which it must pass before it can be used in the arts increases its cost.

One ofthe objects of the present-invention is to produce a substance similar to chicle.

Another object is to provide a simple and practical process for making a substance which may be used as a substitute for chicle, or produce an article or substance that will be cheap to manufacture and entirely free from impurities, taste and poisonous matters.

Another object is to produce. a substance which may be used as a-base for chewing gum, the requirements therefor being considered in hereinafter describing the invention.

Other objects will be in part obvious and in art hereinafter pointed out. I

he invention accordingly consists in the several steps and the relation and order of Application filed April Q5, 1911. Serial No. 823,141.

one or more of those steps with relation to each of the others thereof which will be ex-- emplified .1n the hereinafter disclosed process, and the scope of the application of and triturating the same with dilute soda combined with sugar,': or soda alone, or even sugar alone, and subsequently blowing the same with superheated steam which decoraposes and boils off some of the ingredim.

which contain the taste.

steps. Takinga specific case, for instance, the resin of Pontianak may be conveniently treated as follows: Pontianak resin as sold as a waste product is generally in a granular condition and contains about twentyfive per cent. of moisture and particles of dirt and rubber. The resin is first partiall dried and ground through about an 8-mes screen, when particles of rubber sieve out, and then ground in waterin a pebble mill in the presence of soda and sugar. The water contains about five per cent. of sugar and about one quarter of one per cent. of soda. It is round in the pebble ;mill until the liquor is 1n the form of a sludge containing particles from 60 to 100 mesh. The sludge from the pebble mill is diluted several times with water and then boiled. and filtered, and then washed first with hot water and then with cold water. .The filter cakeis centrifuged and washed in a centrif- -ugal machine and the. resultingv partially The poisonofis principles are also removed during these .is further dried in trays in 'an ordinary drier. The drier product is then melted'and blown with superheated steam until clear,

'or until the vapors which arise indicate that all taste has been removed from the resin.

While blowing the material is kept at about 150 to 180 The melted blown resin is then allowed to cool slowly in order to permit sand and dirt to settle. The resin is then ready to be combined with the other ingredients, which will be taken u in order.

Second: One or several 0 the following varieties, of gutta, are next purified: Pontiting in the hollander is done in the presence of water, preferably containing soda and zinc chlorid either together or separately, according to the condition of the raw gutta, for deodorizing and disinfecting. 4 The soda also prevents stickiness. which is in the material is thus allowed to stiparate and sink by gravity to the bottom 0 the tank of the hollander and floating particles of bark arise to the surface and are skimmed off. Sometimes common salt is added to the water to change the specific gravity so as to make the gutta float, the dirt and sand sinking, thus causing a separation. In warm weather, ice is also added to the water to prevent the rubber or gutta particles from coalescing. The chopped up gutta is then placed n a tank having a cone shaped bottom, with water and salt to remove impurities by gravity. It is then washed and boiled to further remove the' sand which collects in the cone. Also during this stage, somevv guttas are boiled in preferably not less than five per cent. sugar solution in order to remove any objectionable taste. The gutta is then taken from this boiling tank and washed on ordinary washing rolls and hung to dry, and when properly dried the various guttas are combined on the rolls in the various proportions in which they will be later used.

Third: If any rubber is used the finest plantation Ceylon pale crepe is selected. This rubber is first masticated on ordinary mixing rolls and then heated with petrolatum and worked into a solution of rubber and petrolatum. It is then ready to be used in the final compound. This rubber thus prepared can also be used as an alternative for-one or more of the guttas mentioned in the second step if desired.

Part of the sand' Fourth: In making the combination of the resins and guttas which have been purified .ciently low melting point to -soften in the mouth, but. as. a rule they do notsoften enough to chew easily. The resins, especially after being treated to remove their taste and odor, will not soften at the temperature of the body. In order to bring these ingredients down to the proper melting point an oil or fatty substance must be added, which should be of such a character that it will not readily chew out of the mixture. It has been found that many nonsaponifying oils or not easily emulsifying oils will meet this requirement. Such an oil is petrolatum, a petroleum residue, and also blown linseed and other similarly treated oils. Cocoa butter also chews out with difliculty from the mixture. If petrolatum is used as a softening ingredient it must be melted down with the resins and the mixture kept at an elevated temperature until a thorough union and solution of the resinin the petrolatum has occurred. The amount of petrolatum used depends upon the melting oints of the other ingredients.

T echicle substitute as produced should be friable in order to meetthe requirements of the arts In order to obtain this friableness a certain amount of sugar is used in amount of cocoa butter can be added in guttas are added gradually after being first softened and warmed up by immersing in boiling water. By this means the gutta is mixed into the hot resin without chilling the resin, for if chilled there would be chunks of hard resin through the mixed product. A small amount of salt may be also added during mixing because it is found that if salt is not added the person chewing the gum would suffer discomfiture from swallowing so much mixed air and saliva and the salt seems to prevent this excessive secretion and swallowing. Before discharging from the mixing machine the batch may be allowed to cool slightly and air worked into it by revolving the paddles. This makes a more friable product. Another way is to force the finished batch throu h dies.

-In producing a substitute or chicle best adapted to act as a base for chewing gum substantially the following materials in the proportions indicated are used,resin 47% petrolatum, 8 sugar, 11%; cocoa butter, 111-%; Ppntianak, 8% siak gutta, 5%; red Niger gutta, 19%, and salt.

.Itis thus seen that this invention produces a desirable composition of matter having the advantageous features of chicle by a simple, practical and inexpensive process.

As many changes could be made in carryin out the above process without departing from the scope of the invention, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.
